Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603590, here are decompositions:

13 + 31603577 = 31603590
23 + 31603567 = 31603590
37 + 31603553 = 31603590
71 + 31603519 = 31603590
79 + 31603511 = 31603590
101 + 31603489 = 31603590
103 + 31603487 = 31603590
163 + 31603427 = 31603590

Showing the first eight; more decompositions exist.
